Aug. 12, 1958 R. HARTOG SINK. ATTACHMENT Filed Dec. 3. 1956 #vmvron: RQBBERT HARTOG AW'ORNEYS United States Patent SINK ATTACHMENT Robbert Hartog, Toronto, Ontario, Canada, assignor to Kitchen Installations Ltd., Toronto, Ontario, Canada, a corporation of Toront Application December 3, 1956, Serial No. 625,661 2 Claims. (Cl. 4-187) This invention relates to improvements in metal sink bowls, wash basins or the like, of the kind having a flange extending from their top edge and adapted to mask the edges of an aperture in the structural member in which the bowl is mounted.

Such bowls are in common usage, and in prior constructions have been secured in the aperture of the structural member by means of jacks each having one end engaging a projection fast with the bowl, and reacting at their other ends on the underside of the structural member.

While such prior constructions have been satisfactory in use, great difliculty has been encountered in the installation of such bowls in view of the limited and usually inaccessible space available beneath the structural memher, which space also contains water and waste pipes and structural elements supporting the structural member.

An object of the invention is to provide an improved sink bowl of the kind above referred to, in which installation of the bowl is facilitated.

A further object is to provide an improved sink bowl assembly of the kind above referred to incorporating improved jacks.

Further objects and advantages of the invention will become apparent from a study of the following specification when taken in conjunction with the accompanying drawings, in which:

Figure 1 is a perspective view of a sink bowl and its associated jacks according to the invention, a fragment of the structural member also being shown; and,

Figure 2 is an enlarged transverse section through the structural member showing a portion of the sink bowl arrangement in situ.

The sink bowl is provided by a bottom wall 10, side walls 11 to 14, and a flange 15 integral with the side walls at their top edge. As will be observed more particularly from Figure 2, the flange 15 is radiused or beaded at its free edge, as is indicated at 16, to improve the rigidity of the flange and to provide a decorative molding.

The structural member is indicated at 17, and may be of wood surfaced with an abrasion and water resistant synthetic resin or any other suitable material.

Below, and extending substantially parallel to the flange 15 is a metal strip 20, the strip being crimped transversely of its length to define alternate ridges 21 and troughs 22, the ridges 21 being presented to the outer wall of the bowl and being secured thereto'as is indicated at 23 in Fig. 2 in any convenient manner, for example by soldering, spot welding, or brazing. It will be observed that the troughs 22 define with the side walls 11 to 14 of the bowl a continuous series of apertures 24 for the reception of elements of jacks hereinafter fully described.

By providing a continuous series of apertures, the installation of the bowl is greatly facilitated in that the jacks can be located in any one of a great number of positions circumferentially of the bowl, and can there fore be arranged to avoid such obstructions as water pipes or structural elements supporting the member 17.

Also, the jacks can be arranged at positions which facilitate their installation should the space beneath the struc-;-

tural member be particularly inaccessible. r The jacks are provided by an L-shaped-element 25 one limb 26 of which is adapted to be received in an aperture 24, and the other limb 27 of which is provided 1 with a threaded hole in which is received a threaded rod 28. The rod 28 is provided with a means, for example, a hexagonal head 29, by means of which can be conveniently rotated, and at its end which is to engage the underside of the structural member may be provided with a rotatable dished washer 30 to minimize damage to the structural member 17.

To install the sink bowl in the aperture, the bowl is lowered through the aperture, the troughs provided by the strip 20 being of less extent than the aperture itself, the edges of which are indicated at 30 in Figure 2. The elements 25 are then positioned adjacent the washer 30 of the rods 28, and the limbs 26 are hooked into a convenient one of the apertures 24, after which the rods 28 are rotated in an appropriate direction to cause them to advance towards the structural member 17, which they eventually engage to force the strip 20 downwardly and thus force the flange 15 into intimate contact with the upper surface of the structural member 17.

It will be noted that the jacks greatly facilitate the installation of the sink bowl where the space available is restricted, for the limbs 25 can easily be hooked into the aperture even when the aperature is not itself visible, in which case the lower end of the limb 26 would ride on the edge of the strip presented to the flange until such time as the limb became aligned with an aperture into which it could drop.

While a single construction according to the invention has been described in the foregoing specification, it will be appreciated that various modifications may be made without departing from the spirit of the invention or the scope of the appended claims.

What I claim as my invention is:

1. A sink bowl of the kind having a bottom wall, a peripheral side wall, and a flange extending outwardly of the peripheral side wall and adapted to mask an edge of an opening in a structural member in which the bowl is to be mounted, in combination with a strip encircling the peripheral side wall substantially parallel to the flange, the strip being crimped transversely of its length to provide a continuous series of alternate ridges and troughs, the portions of the strip providing the ridges being of less length than the portions of the strip providing the troughs and being presented and secured to the peripheral side wall for the portions of the strip providing the troughs to define with the peripheral side wall a continuous series of apertures for the reception of an element of a jack, the portions of the strip intermediate the ridge and trough providing portions extending outwardly of said peripheral side wall for that edge of the strip adjacent the flange of the bowl to provide a guide for the said jack element when that element is abutted against that edge.

2. A sink bowl of the kind having a bottom wall, a peripheral side wall, and a flange extending outwardly of theperipheral side wall and adapted to mask an edge of an opening in a structural member in which the bowl is to be mounted, in combination with a strip encircling the peripheral side wall substantially parallel to the flange, the strip being crimped transversely of its length to provide a continuous series of alternate ridges and troughs, the portions of the strip providing the ridges being of less length than the portions of the strip pro- Pat'ented Aug. 12, 1958 viding-thetr0ughs-- and being presented and secured to the peripheral side wall for the portions of the strip providing the troughs to define with the peripheral side wall a continuous series of apertures for the reception ofen element da jaelg'the portions of the 'strip' intermediate'th'e ridge and trough providing portions extending outwardly of the peripheral side wall for that edge-of the-stripadjace'nt 'the flange of'the bowl to provide-a guide for the said jackelement when that" element is abutted'against that edge, and a plurality of jacks each 10 comprising-a threaded rod, a member threaded on the rod,'-an'd' a limb tast'with each member and providing said element for reception in said'aperture, said limb aperture.
